Mepivacaína Braun (Mepivacaine Hydrochloride)

Mepivacaine Hydrochloride is used in clinical settings to achieve local and regional anesthesia through sodium‑channel blockade.

• Local anesthesia: produces temporary loss of sensation for minor surgical or dental procedures.
• Epidural analgesia: provides pain relief during labor, childbirth, or postoperative recovery.
• Intramuscular anesthesia: enables muscle block for diagnostic or therapeutic interventions.

• Mepivacaine Hydrochloride acts by reversibly binding to voltage‑gated sodium channels on neuronal membranes, stabilizing the inactive state of the channel and preventing the influx of sodium ions. This inhibition blocks the generation and propagation of nerve impulses, resulting in a temporary loss of sensory and motor function in the targeted area.

Mepivacaine Hydrochloride may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Injection site pain or burning sensation
• Mild hypotension or dizziness
• Nausea or metallic taste
• Transient tremor or muscle twitching
• Headache
• Light‑headedness

Serious or Rare Side Effects

• Allergic reactions including anaphylaxis
• Cardiac arrhythmias or conduction disturbances
• Central nervous system toxicity such as seizures
• Prolonged or profound nerve block
• Methemoglobinemia
• Respiratory depression or apnea

When using Mepivacaína Braun, clinicians should observe specific safety measures to minimize risk.

• Patient assessment: evaluate cardiovascular and hepatic status before administration.
• Dose adjustment: reduce concentration in patients with liver impairment or advanced age.
• Contraindications: avoid in individuals with known hypersensitivity to amide‑type local anesthetics.
• Monitoring: observe for signs of CNS toxicity, hypotension, or arrhythmia during and after injection.
• Drug interactions: review concurrent medications that affect sodium channels or CNS function.
• Store at ambient temperature: keep in original container, protect from light and moisture.

Mepivacaine Hydrochloride can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Class I antiarrhythmics (e.g., quinidine, procainamide): may potentiate cardiotoxicity.
• Other local anesthetics: increase risk of systemic toxicity.
• Systemic CNS depressants (e.g., barbiturates, benzodiazepines): enhance central effects.
• Beta‑adrenergic blockers: may exacerbate hypotensive response.
• MAO inhibitors: risk of severe hypertension.

Moderate Interactions (Monitor Closely)

• Epinephrine: can prolong block duration and affect cardiovascular response.
• Calcium channel blockers: may increase myocardial depression.
• Diuretics: potential for altered plasma protein binding.
• Lithium: heightened risk of neurotoxicity.
